The World Health Organization was notified on December 31, 2019, that a cluster of pneumonia patients with an unknown origin had been discovered in Wuhan City, Hubei Province, China. Severe acute respiratory syndrome coronavirus 2 caused the pneumonia (coronavirus disease 2019 [COVID-19]). Fever, dry cough, and shortness of breath are among the most prevalent symptoms described by COVID-19 patients. In this case series, we discuss three cases of patients presenting with deep vein thrombosis for which they underwent inferior vena cava filter placement with thrombolysis and mechanical thrombectomy. These cases were unusual as they belong to the moderate category of COVID rather than severe category which commonly presents with coagulopathy.

Background: Bariatric surgery is the most effective weight loss intervention for patients with severe obesity. Several studies have shown wide variability in weight loss response between patients. The aim of the study is to identify comparative poor responders based on weight loss in the early postoperative period. Methods: A retrospective analysis of 125 patients who underwent primary bariatric surgery by a single surgeon and completed 1 year of follow-up was performed. Patients were divided into two groups based on % Total Weight loss (%TWL) at 1 month after surgery: Group 1-who lost <10% TWL and Group 2-who lost >10% TWL. The comparison of factors in both groups at different time points was executed using paired t-tests or analysis of variance. The relationships between Group 1 and Group 2 after 1 year follow-up period were assessed through linear regression analyses. Results: Seventy (56%) patients lost <10% TWL and 55 (44%) patients lost more than 10% TWL in 1 month after surgery. Mean weight loss at 1 month and 1 year after surgery was 9 ± 5.5 kg and 37 ± 13.3 kg in Group 1 compared to 16 ± 5.2 and 46 ± 16.4 kg in Group 2, respectively. Patients with >10%TWL at 1 month had significantly greater %TWL at 1 year (P = 0.001). Linear regression analysis showed a positive correlation between patients who lost >10%TWL 1 month after surgery and weight loss at 1 year. Conclusion: Postoperative percentage TWL of <10% at 1 month can be used as an early determinant of comparatively poor weight loss at 1 year. Early initiation of aggressive and multimodal treatment strategies is likely to improve overall weight loss outcomes after surgery.

Background: Bariatric surgery leads to a significant improvement in obesity and associated comorbidities. Safe surgical outcomes are especially desirable in bariatric, as most patients perceive it as an aesthetic surgery, while an intestinal/gastric surgery may be associated with morbidity. A detailed pre-operative evaluation is required to avoid surgical surprises and post-operative complications. Besides other routine investigations, pre-surgery upper gastrointestinal (GI) endoscopy has always been a topic of debate. Some surgeons perform it routinely before the surgery, whereas others perform it selectively. It is mostly accepted that pre-operative diagnosis of gastro-oesophageal reflux disease could change the plan of surgery in favour of Roux-en-Y gastric bypass although similar consensus does not exist in favour of Sleeve gastrectomy if a gastric/duodenal pathology is detected pre-operatively in a planned roux-en-y gastric bypass patient. Aim: Through this case series, we want to highlight the role of routine pre-operative upper GI endoscopy in selecting the bariatric surgery. Cases: We present four cases, from amongst many others, where endoscopy changed the course of bariatric surgery. Conclusion: Upper GI endoscopy should be performed before bariatric surgery, even in asymptomatic patients, to avoid post-operative surprise/complication.
